CTest: Do not truncate UTF-8 test output too early (#10656)

Since commit e4beefeb (CTest: Do not munge UTF-8 output in XML files,
2009-12-08) we validate UTF-8 encoding of build and test output as it is
written to XML files.  However, in cmCTestTestHandler::CleanTestOutput
we still processed test output one byte at a time and did not recognize
multi-byte UTF-8 characters.  Presence of such characters caused early
truncation.

Teach CleanTestOutput to truncate test output at the limit but without
cutting it in the middle of a multi-byte encoding.  Also, stop avoiding
truncation in the middle of an XML tag like "<MyElement>" because the
'<' and '>' will be properly escaped in the generated XML anyway.
